zorax2 Posted January 21, 2016 Posted January 21, 2016 After nearly 2 years of my 50+ device system functioning flawlessly, my PowerLinc modem failed. I just installed the new 2413S modem and it can only communicate with a few devices on my network. I'm so frustrated! I've made no other changes to my system and simply plugged it into the wall and re-attached the Ethernet cable between the PLM and ISY. I've also tried the reset on the PLM (press and hold set button until beep stops) and have power cycled the ISY. I really don't have any other outlets available as this is in a wiring closet and I have my IR emitter there which is hardwired to multiple RF receivers throughout the house. My electrical panel has a SignalLinc phase coupler in it. Is it possible there is some kind of flaw in my new 2413S modem? What things can I do to fix this situation?
LeeG Posted January 21, 2016 Posted January 21, 2016 (edited) Go to this link, Scroll down to section for replacing PLM. There are specific power off, power on, and actions required to replace PLM http://wiki.universal-devices.com/index.php?title=ISY-99i/ISY-26_INSTEON:File_Menu Edited January 21, 2016 by LeeG
zorax2 Posted January 21, 2016 Author Posted January 21, 2016 Thanks Lee - I thought the modem was simply a communication device and had no idea it stored information. I installed the new modem following the instructions on the link you provided and everything went well and things seem to be working fine. HOWEVER - I woke up this morning and think I might have messed up. The instructions give the warning: Never replace your PLM while the ISY is running because it will assume it is still connected with the old PLM. The ISY will appear to work, but it will be writing the address of the old PLM into the device links, thus you will not see devices updates etc. I think I may have plugged in the new PLM while the ISY was running in one of my earlier attempts to get things working which my have resulted in writing the address of the old PLM into the device links. Should things be okay given everything seems to be working fine? Or should I use "Delete Modem" to remove this modem, restore a previous backup, use "Delete Modem" to remove the failed modem and then finally use "Restore Modem" to re-install the new modem? Should the "Restore Devices" command be used to re-establish the all the information as stored in the ISY?
LeeG Posted January 21, 2016 Posted January 21, 2016 NEVER Delete Modem. The issues you have now will be nothing to those if PLM is Deleted. If the Restore Modem (PLM) did not resolve after going through power off, power on, in Wiki instructions, the next step would be a File | Restore Devices. However, what actual symptom do you have.
zorax2 Posted January 21, 2016 Author Posted January 21, 2016 Fortunately, I'm having no problems or symptoms. I'm simply concerned that I might have replaced the PLM while the ISY was running and the web page stated that the address of the old PLM will be written into the device links. "Never replace your PLM while the ISY is running because it will assume it is still connected with the old PLM. The ISY will appear to work, but it will be writing the address of the old PLM into the device links, thus you will not see devices updates etc." Perhaps there is no problem at all. Is there any benefit to running File | Restore Devices if everything seems to be working fine? Thanks
LeeG Posted January 22, 2016 Posted January 22, 2016 I would not bother but there is no harm in issuing Restore Devices besides the time and effort, particularly with battery devices that must be updated on at a time. You can spot check a few device link databases. Run a Show Device Links Table for a KPL, a SwitchLinc and see if any of the link records have the old PLM address.
zorax2 Posted January 22, 2016 Author Posted January 22, 2016 Great advice. As always - thank you very much for sharing your expertise!
